If you'll forgive my unsolicited opinion on vape forum advice, the #1 thing IMO is this...
Vapers can be divided into 2 distinct groups. The ex-smokers and the... "others".
The ex-smokers generally vape MTL style. (mouth to lung, like a cigarette) The "others" (cloud chasers, etc) do direct lung inhales.
My advice is to vape MTL. .5 ohms might be a lil warm. Anything below 1 ohm is considered Sub-ohm vaping, the lower, the hotter.
When you read forum posts, it is important to know which type of vaper is talking, and whether they are in common with you.
IOW, I am an ex-smoker, so I lend faarr more credence to posts written by ex-smokers.
Cloud chasers needs are completely different from mine. A perfect example is the Tobeco Supertank. People are absolutely gushing over it! But if you read closely, (and search the posters' histories) you'll see the device is not really a great MTL device at all... but maann, can it chuck sum cloudz!
It does take a little time to figure out whose vape tastes and styles are the most similar to yours.
Most ex-smokers crave 'throat hit'. We wanna feel that lump of vapor as we inhale. You will not get that with direct lung inhale.
What strength (mg nic) juice are you vaping?
